A great application for this is in randomizing playlists. My friends, who are also CS grads and should know better, have often complained that their MP3 players, CD carousels, etc play the same music too often claiming that the random is broken, when a song repeating in a short period of time or other songs never playing is what you would expect from a truly random selection. Using this algorithm, you'd be sure to hear all of your songs. I'm guessing most music services already do something like this.
